That other chromosome exists only so that it instils in us women the uncanny ability to always ask questions such as this to keep you men on your toes ... and looking after us.
Day to day, even if you answer the exact same question the exact same way - our reaction to it WILL change based upon whether:
1) We want to get lucky too;
2) Whether it happens to be that week;
3) Whether it happens to be the week before that week;
4) Whether it happens to be the week after that week;
5) Whether t happens to be the week that we are PMSing because of that week; OR
6) Just because we're girls and so WE CAN.
I think that explains it fully and looks after the entire month. Have a great day gentlemen!!
Kisses to you all ...
